Flanger over an open, chiming riff proves the tone is not just gain; the chord voicings ring because the distortion is less compressed than modern high-gain.
A serious working guitar built around speed, stability and high-output rock tones. The compound-radius neck makes fast legato feel effortless, and the bridge humbucker is voiced tight enough that palm mutes stay defined under heavy gain instead of turning to mush.
The template for British rock. Little gain on paper, enormous attitude in practice — the crunch happens because the power section is being asked to do something it barely wants to do.
The modern metal standard. Saturated but tight, with a midrange that cuts through a loud band and a lead channel that turns sloppy technique into an audible confession.
